Comparative Analysis of Digital Image Watermarking using DCT and DWT
Abstract: AbstractWatermarking is a technique to hide information into digital data and provides security against intentional and unintentional attack. It is a very important and emerging field which helps to protect ownership of digital information. Watermarking is the process of inserting or hiding information behind cover data. In this paper we discussed about two digital watermarking techniques, Discrete Cosine Transform (DCT) and discrete wavelet Transform (DWT). The parameters to test robustness …

Image Steganography Using Multi-level Hiding Technique
Abstract: ABSTRACTSteganography is the art of hiding secret information in the innocent-looking cover media but the concern of the sender of the secret data remains that the secret communication embedded should not be deciphered by a hacker or examiner. Presently, single level of hiding of the secret message in the cover medium is resorted to. This paper presents a novel idea of multi-level hiding (MLH) of the secret information in the …

An Enhanced RSA Cryptography and Steganography using 1-2-4 LSB Algorithm
Abstract: AbstractSteganography is the approach of the hidden information this is used for the detection of hidden know-how prevents. As the requirement of protection and privateness increases, the need of the hiding private information is ongoing. For color images, we are using 1-2-4 LSB on RGB component, then encrypt data using RSA approach. We calculate peak signal noise ratio for quality and brightness. In this approach, first the information is in …

Font-Based Text Steganography for Covert Communication in Devanagari Script: A Review (2020–2026)
Abstract: Steganography hides the fact that a communication exists rather than merely safeguarding its content. Text is the most challenging of all steganographic media because it contains the least redundancy and is the most sensitive to changes. Devanagari script, with its conjunct consonants, ligatures, matras, and non-linear glyph construction, makes these difficulties even harder, rendering rendering-dependent and OCR- based steganographic methods largely ineffective. This paper presents a systematic review of text …
